What is the role of phytoplankton in the carbon cycle? (2020)

Step 1: Understand what phytoplankton are. They are tiny plants that live in the ocean.
Step 2: Learn that phytoplankton use sunlight to make their food through a process called photosynthesis.
Step 3: During photosynthesis, phytoplankton take in carbon dioxide (CO2) from the water and air.
Step 4: As they absorb CO2, they help reduce the amount of carbon dioxide in the atmosphere.
Step 5: When phytoplankton die, they sink to the ocean floor, taking the carbon with them. This process is called carbon storage.
Step 6: By storing carbon, phytoplankton help regulate the Earth's climate and keep the carbon cycle balanced.
